Medulla oblongata controls:

1. Smelling
2. Beating of heart and respiratory movement
3. Intelligence and will power
4. Balancing of the Body

Beating of heart and respiratory movement

Reason — Involuntary functions of internal organs are controlled by Medulla oblongata.
Smelling is controlled by the olfactory part of the brain (olfactory bulb and cerebrum), not the medulla oblongata. Intelligence and will power are controlled by the cerebrum, which is responsible for thinking, memory, and decision-making. Balance and coordination are controlled by the cerebellum, not the medulla oblongata.
